Hi All,

We're getting CPU spikes due to snmp process ID 222 randomly, lets say 5 mins, may be due to polling period. The ios is 3845-advipservicesk9-mz.124-25g

Please help in fixing the same.

show run | in snmp

show proc cpu sort | in snmp

show stacks 222

show snmp

 

regards

Hello,

 

you are running a very old IOS on a very old router. That doesn't necessarily mean that this automatically causes the issue, but if you can, upgrade your IOS.

 

What is the output of:

 

show snmp stats oid

 

Usually, one of the OIDs polled causes the problem. The output shows you which OIDs were being polled last, try and match that with the time the spike occurred...

show snmp stats oid -> I had tried this command earlier, but found does not exist/invalid.

Apart from upgrade of the image, where you able to find out from show stacks 222 ?

I remember couple of years ago, had fixed by executing snmp-view command to cut few parameters.

Anything clicks from your experience ?

Thank you.

Anybody pls help.
